Ag₂Mo₃O₁₀ Nanorods Decorated with Ag₂S Nanoparticles: Visible‐Light Photocatalytic Activity, Photostability, and Charge Transfer

Abstract

Ag2Mo3O10 nanorods decorated with Ag2 S nanoparticles have been synthesized by an anion-exchange route. With thiourea as the sulfur source, sulfur ions replace [Mo3O10](2-) units of active sites on the surface of Ag2Mo3O10 nanorods, forming Ag2Mo3O10 nanorods decorated with Ag2S nanoparticles. This induces enhanced absorption in the visible-light region. Ag2 S nanoparticles decorate the surface of Ag2Mo3O10 nanorods uniformly with a suitable amount of thiourea. The Ag2S/Ag2Mo3O10 nanoheterostructure enhances the photocatalytic activity on the degradations of Rhodamine B and glyphosate under visible light. This enhancement is attributed to the improved absorption of visible light and effective separation of charge carriers in the nanoheterostructure. Meanwhile, the Ag2S/Ag2Mo3O10 nanoheterostructure displays good photocatalytic stability based on cyclic photocatalytic experiments.

Easy Scale‐Up Synthesis of Mo8O26(C5H6N)4.H2O Hybrid with a Rectangular Prism Morphology and Its Application as an Efficient and Highly Recyclable Bi‐functional Catalyst for Knoevenagel Condensations

“…The peaks in the region 800–980 cm −1 were attributed to the different stretching modes of Mo–O and Mo=O. Also, various forms of vibrational modes, including bending, scissoring, and wagging were detected in the range of 400 cm −1 and below ,…”

Samarium and Nitrogen Co‐Doped Bi2WO6 Photocatalysts: Synergistic Effect of Sm3+/Sm2+ Redox Centers and N‐Doped Level for Enhancing Visible‐Light Photocatalytic Activity

“…The stability of a photocatalyst is important for its practical application . To test the stability of the Sm‐N‐Bi 2 WO 6 photocatalysts, cycling experiments of RhB degradation were evaluated and are shown in Figure C. The photocatalytic degradation efficiency of Sm‐N‐Bi 2 WO 6 photocatalyst decreased slightly after four successive cyclic reactions.…”

Scaled‐up, selective and green synthesis of sulfoxides under mild conditions using (CeIII‐MoVI)Ox/aniline hybrid rods as an efficient catalyst

“…The peak around 3375 cm −1 is assigned to ν (N-H), and the band near 1620 cm −1 may be due to single H-O-H bending vibrational mode of absorbed water. Furthermore, the various forms of vibrational modes, including bending, scissoring, and wagging were detected in the range below 400 cm −1 [63][64][65][66] The peak at 923 cm −1 should be assigned to the Ce-O-Mo or Ce-O-Ce stretching mode. [61] The [1] The band at 904 cm −1 can be attributed to ν (Ce-O-Mo) or ν (Ce-O-Ce).…”
